FB marketplace

Hi, i recently created fb account and was able to post only 1 time per day on marketplace but yesterday that changed and i can post more idk how much but i did 7listings yestarday and still could add more, my question is, is it safe to add lisitngs until my limit is reached per day even if its like 50 or should i not do that because it could be spamy or something else and my acc would get banned? please only answer if u know this stuff

oh i reached my monthly listing limit which is 20 so theres no point in this thread
